On-Board Computer

• Distance 

  Entered manually using the controller and then computed (counted down) by the instrument cluster or transferred by the navigation system via MOST to the instrument cluster. In this case, the navigation system handles the calculation up to the position "0"; from then on (minus distance), the instrument cluster continues the count in both cases.

• Range 

  Calculated from the average fuel consumption figure and the tank contents. A calculation compensates for idle periods with the engine running or sudden changes in driving style. The average fuel consumption figure is a calculated result which, depending on the driving situation, revises the current fuel consumption over a given period. This ensures that the calculated results are plausible and that large jumps are avoided if vehicle handling changes suddenly.

• Arrival time 

  Calculated from distance, time and an average speed. Here, too, the calculation method ensures equalization of the average speed so that there are no larger jumps in time; the displayed value grows or shrinks minute by minute. The arrival time can only be calculated when the clock has been set and a distance entered.

  If no distance is entered manually, but is adopted from the navigation system, there is a permanent alignment with the route guidance on the basis of the roadmap data. The result is a significantly more precise prediction of the arrival time.

• Average fuel consumption 

  The calculation interval always begins with a manual reset; the display appears after arrival of the speed signal. The basis of the calculation is the data from the consumption and travel memory.

• Average speed 

  Here, too, each calculation interval begins with a manual reset; the display appears after arrival of the speed signal. The basis of the calculation is the data from the consumption and timer.

The reset of average fuel consumption and speed is by means of the controller, directly in the menu of the on-board computer in the Control Display. When one of these displays is selected, a dialog window appears on the screen to enable a selective reset.

Individual items of information of the On-Board Computer can also be displayed in the instrument cluster:

• Distance
• Fuel gauge (tank contents can only be viewed in KOMBI)
• Range

-can be displayed in the display field below the speedometer,

• Arrival time
• Average fuel consumption
• Average speed
• Total mileage Can only be viewed in the instrument cluster 
• Distance to destination Can only be viewed in the instrument cluster 
• Current consumption Can only be viewed in the instrument cluster 

-can be displayed in the display field below the tachometer.

The functions Stopwatch, Limit and Memo as well as the timer for independent ventilation are only provided in the Control Display. They cannot be displayed on the instrument cluster.

When the vehicle is started, the information that was last selected will be displayed. If the display area below the tachometer contains a Check Control message, no function of the On-Board computer is displayed there.

The displays of the On-Board Computer are scrolled and shown in the instrument cluster by means of buttons in the turn signal stalk. Pressing and holding the top (1) button toggles between Check Control and On-Board Computer in the display area below the tachometer. Briefly tapping scrolls through its functions.

Briefly tapping the lower button (2) scrolls all the display options in the display area below the speedometer.

Pressing and holding darkens both display areas. Darkening is not possible when a Check Control message is active or the fuel gauge is at reserve. A single display area cannot be darkened, the fields are always active or dark as a pair.
